DISCONNECTX(2)						      BSD System Calls Manual						    DISCONNECTX(2)

NAME
     disconnectx -- disconnects a connection on a socket

SYNOPSIS
     #include <sys/socket.h>

     int
     disconnectx(int socket, sae_associd_t associd, sae_connid_t connid);

DESCRIPTION
     The parameter socket is a socket.	The communication domain of the socket determines the availability and behavior of disconnectx().  For
     connection-oriented socket, disconnectx() is analogous to shutdown(2) with SHUT_RDWR issued on the socket. For connectionless socket, it dis-
     associates any existing association to the peer socket.

     The parameter associd specifies the association identifier.  It should be set to SAE_ASSOCID_ANY.

     The parameter connid should be set to SAE_CONNID_ANY.

NOTES
     disconnectx() is currently supported only on AF_INET and AF_INET6 sockets of type SOCK_DGRAM and SOCK_STREAM.

RETURN VALUES
     The disconnectx() function returns the value 0 if successful; otherwise the value of -1 is returned and the global integer variable errno is
     set to indicate the error.

ERRORS
     The disconnectx() system call succeeds unless:

     [EALREADY] 	Operation already in progress.

     [EBADF]		Socket is not a valid descriptor.

     [EINVAL]		The associd or connid argument is invalid or the underlying protocol is no longer attached to socket.

     [ENOTCONN] 	The socket is not connected.

     [ENOTSOCK] 	Socket is a file, not a socket.
